As I was puttering around putting together an overnight bag and the laptop in a backpack for him, the VogonMom called because she's in town and wanted to get together sometime. I told her what was going on (she's a nurse), gave her the information I had and she called him while I went back to getting things together. She called back to relay that he thinks he might be getting out tonight so she'd head over to the hospital and will call me with more information later.

...

I'm itching with curiosity to find out what the docs think might have happened. Below normal potassium and slightly elevated liver enzymes are normal for him, but low levels treated with 12+ hours of IV potassium is new to me.

I've updated again; he's still getting potassium and there may be something anomalous at the site of his 2005 head injury. Probably unrelated to the crockpot, but of course nothing definitive yet.

His parents are here (unrelated to his situation, they just came into town this weekend -- good timing) and we're heading up to the hospital with an overnight bag for him and the laptop (if he wants it).
